"I'm feeling good," Ginobili said. "I just want to feel even better and play more."

Yao made eight of his 10 shots and had five rebounds and was impressive running the court. He showed no sign of the injury to his left foot that ended his NBA season in February and threatened his Olympic participation.

Yao returned to light training late last month after tests in Houston showed his recovery was on schedule and he was about 80 percent healed. Such injuries usually take a year to fully heal.

Yao didn't score until nearly halfway through the second quarter. He then combined with former Shanghai Sharks teammate Liu to put China ahead 40-37 at the half.

The win avenges a 72-71 loss to Angola in an Olympic warmup tournament this month. The teams face each other Group B at the Olympics along with Germany, Greece, Spain and the United States.

China coach Jonas Kazlauskas said he would continue to play Yao for 25-30 minutes a game, but would also rely on former Dallas Mavericks center Wang Zhizhi to fill gaps. Wang had five points in about 22 minutes, while forward Yi Jianlian, recently acquired by the New Jersey Nets, had 11 points.
